Abstract (en)
A relief printing original plate for rotary letterpress printing wherein at least an adhesive layer, a photosensitive resin layer and a cover film are successively layered on a support, wherein the photosensitive resin layer contains at least a synthetic rubber-based polymer, a photopolymerizable unsaturated compound and a photopolymerization initiator, and Shore A hardness of a surface of the photosensitive resin layer after photo-curing is 80 to 95. Preferably, the synthetic rubber-based polymer is a hydrophobic polymer obtained from a water-dispersible latex having a weight-average gelation degree of 50 to 80%. Preferably, the photosensitive resin layer contains 20 to 70% by mass of the synthetic rubber-based polymer. The relief printing original plate is suitably used for a rotary printing machine of a center drum type.
